    • An introduction to the statistical theory of polymer network formation 
      Chapitre d'ouvrage scientifique
      GILORMINI, Pierre (Nova Science Publishers, Inc., 2011)
      A short but detailed introduction to the statistical theory of polymer network formation is given, including gel formation, gel structure, and sol fraction. Focus is put on the use of probability generating functions, and ...
    • The effect of applied stresses on the equilibrium moisture content in polymers 
      Article dans une revue avec comité de lecture
      GILORMINI, Pierre; ccDERRIEN, Katell (Elsevier, 2007)
      The relation between saturation moisture content in a polymer and applied stresses is derived as a function of the coefficient of moisture expansion. The model predictions are compared favourably with experimental data ...
    • Empirical Natural Closure Relation for Short Fiber Suspension Models 
      Article dans une revue avec comité de lecture
      ccPRULIERE, Etienne; ccAMMAR, Amine; ccCHINESTA SORIA, Francisco (Lavoisier, 2007)
      This work focuses on the resolution of the Fokker-Planck equation that governs the evolution of the fibers orientation distribution. To reduce the computing time, that equation is solved along some flow trajectories in ...
    • Rotational Moulding of Thermosets: Understanding of a Reactive Forming Process 
      Communication avec acte
      VIALE, Jérémy; NONY, Fabien; MAZABRAUD, Philippe; GERARD, Jean-François; DOULIN, Gwenaël; ccTCHARKHTCHI, Abbas (SpringerLink, 2008)
      Physical and chemical transformations of polyurethane thermoset are studied by means of thermal analysis, infrared spectrophotometer and dynamic rheology. Gel point, which limits the material flow, is given as a function ...
    • Towards a high-resolution numerical strategy based on separated representations 
      Article dans une revue avec comité de lecture
      ccCUETO, Elias; GONZALEZ, David; ccAMMAR, Amine; ccCHINESTA SORIA, Francisco (Springer Link, 2008)
      Many models in Science and Engineering are defined in spaces (the so-called conformation spaces) of high dimensionality. In kinetic theory, for instance, the micro scale of a fluid evolves in a space whose number of ...
    • Some Incipient Techniques For Improving Efficiency in Computational Mechanics 
      Communication avec acte
      ccAMMAR, Amine; ccCHINESTA SORIA, Francisco (SpringerLink, 2008)
      This contribution presents a review of different techniques available for alleviating simulation cost in computational mechanics. The first one is based on a separated representation of the unknown fields; the second one ...
    • Recirculating Flows Involving Short Fiber Suspensions: Numerical Difficulties and Efficient Advanced Micro-Macro Solvers 
      Article dans une revue avec comité de lecture
      EL KISSI, Nadia; ccPRULIERE, Etienne; ccAMMAR, Amine; ccCHINESTA SORIA, Francisco (Springer Link, 2009)
      Numerical modelling of non-Newtonian flows usually involves the coupling between equations of motion characterized by an elliptic character, and the fluid constitutive equation, which defines an advection problem linked ...
